Water feeding pipe connector capable of being opened and closed manually

Abstract

The invention discloses a water feeding pipe connector capable of being opened and closed manually. The water feeding pipe connector is used for connecting a train water injection nozzle with a water feeding pipe of water feeding equipment and comprises a connector main body, a switch ring, a valve element, a water sealing plate and a transmission piece, two ends of the connector main body are connected with the train water injection nozzle and the water feeding pipe; the switch ring is arranged on the outer side of the connector main body in a sleeving mode, the valve element and the water sealing plate are both arranged on the inner side of the connector main body, the valve element makes contact with the water sealing plate, and a plurality of corresponding water outlet holes are formed in the contact surface of the valve element and the water sealing plate; the switch ring is fixedly connected with the valve element through a plurality of transmission pieces, and a plurality of notches are formed in the side surface of the connector main body, so that the transmission pieces can penetrate through the notches and can rotate within a certain range. A user can drive the valve element to rotate between the opening position and the closing position by rotating the switch ring, when the valve element is located in the opening position, the valve element communicates with the water outlet holes in the water sealing plate, and when the valve element is located in the closing position, the valve element and the water outlet holes in the water sealing plate are closed.

Description

technical field [0001] The invention relates to the train water supply field, in particular to a water supply pipe joint that can be opened and closed manually. Background technique [0002] At present, after the passenger train enters the station, the operation of adding water to the carriages needs to be completed manually. The main steps include: before the water is filled, the water supply staff connects the rubber water guide pipe of the ground well to the cone-shaped water injection nozzle on the car body, and then opens the water supply valve. Water; after the water supply is completed, the water supply staff will close the water supply valve, and then manually pull out the water guide pipe. The disadvantages of this water supply method are as follows: First, it is difficult to achieve fastening and connection. There are various types of conical water injection nozzles for passenger trains, and the size of the nozzle of the ground aqueduct is relatively fixed, so it i...

Problems solved by technology

The disadvantages of this water supply method are as follows: First, it is difficult to achieve fastening and connection. There are various types of conical water injection nozzles for passenger trains, and the size of the nozzle of the ground aqueduct is relatively fixed, so it is troublesome to connect, and it is difficult to achieve a good fit. Second, due to the troublesome connection and the tight time for water supply, the psychological burden on the water crew is heavy, and the labor intensity of taking over is high; the third is that the opening and closing of the water supply and the speed of the water supply are difficult to control, and water leakage may occur, resulting in a large amount of water waste
